Today I received a call from one of my past clients who I had the listing of last year.  We had the property listed for six months last year and it did not sell, partly due to the listing being slightly over priced, and the other part due to the changing economy and falling housing market.  So we took the property off the market and my seller decided to rent out the property instead.  But through out the past year, my seller and I kept in constant contact, she would ask me for advice about how much rentals are going for per month, I would call to see how she was doing with the house, etc. 

But today, she called me and was tired of dealing with the tenants and now she would like me to list the property again.  So I am in the process of writing up the listing agreement as we speak. 

This goes to show that if you keep in contact with your clients and have a good relationship with them, they will come back to you for the excellent service that you provide.
